History

Kisarazu Air Field was originally established in 1936 as a base for the Imperial Japanese Navy Air Service, subordinate to the Yokosuka Naval District. It was home to the Kisarazu Air Group, the Imperial Japanese Navy's first dedicated land-based bomber unit, which saw extensive combat during the Second Sino-Japanese War and World War II. The base was also used for training, and the testing of experimental aircraft, including Japan's first jet-powered aircraft, the Nakajima Kikka.

After the end of World War II, from September 1945 the base was used by the United States Air Force as "Kisarazu Air Base". In 1956, the base was officially transferred to the control of the Japan Air Self-Defense Force (JASDF) and was used as a training base; although USAF units remained on the base in a tenant capacity until transferred to Tachikawa Air Base in 1961. Subsequently, American assets at Kisarazu came under the control of the United States Navy. In 1968, the JASDF relocated to Iruma Air Base, and Kisarazu was transferred to the control of the Japan Ground Self-Defense Force. Remaining United States Navy assets were transferred to United States Fleet Activities Yokosuka from 1975, and there is currently no American presence at Kisarazu; however, under the terms of the Treaty of Mutual Cooperation and Security between the United States and Japan, Kisarazu Air Field remains available for use by aircraft of the United States 7th Fleet under the name "Kisarazu Auxiliary Landing Field".

The base will be used for maintenance of V-22 Osprey aircraft operated by the United States Marine Corps from MCAS Futenma in Okinawa. Maintenance of the aircraft at Kisarazu will begin in 2015 and will be provided by Kawasaki Heavy Industries.
